nibbles its front feet, paying special attention 

 to the pads, meanwhile holding the foot to its 

 mandibles with the aid of the palpi. But once 

 washing is not enough; I have seen a katydid 

 go over the same foot a dozen times in succes- 

 sion, beginning always with the hind spurs of 



The front portions of the wings the tibia and nibbling along the tarsus to the 



claws. It cleans its face with its front foot, 

 drawing it downward over the eye and then 

 licking it clean. It cleans its antenna with 



its mandibles by beginning at the base and drawing it up in a loop as fast 



as finished. After watching the process of these lengthy ablutions, we 



must conclude that the katydid is among the most fastidious members of 



the insect "four hundred."
